WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 484,652, dated October 18, 1892.

Application filed December 31. 1891. Serial No. 416.623. (No model.)

To all whom it may concern:

Be it-known that I, JOHN CLAYTON, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and usefullmprovementsin Wheel-Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective view showing the entire plow, looking from the landside. Fig. 2 is an enlarged plan of the front portion of the plow. Fig. 3 is a side elevation of the same. Fig. 4 is a transverse vertical section on the line a; as, Fig. 3. Fig. 5 is aside elevation of the rear portion of the plow. Fig. 6 is a detail of the forward portion of the plow, showing in full lines the positions of the parts when the plows are leveled up and in dotted lines the positions when the plows are out of the ground. Fig. 7 is a similar view showing the positions of the parts when the plows are in the ground to their full depth. Fig. 8 is a detail showing the manner of connecting the operating-lever, and Fig. 9 is a detail showing the connection between the connectingrod to the rear wheel and its operating mechanism. A

This invention has relation to certain new and useful improvementsin wheel-plows; and it consists in the novel construction and combination of parts, as hereinafter described, and pointed out in the claims.

In the accompanying drawings, the letters A and B designate,respectively, the land and furrow beams, connected near their forward ends by the curved rectangular ribbed brace A, secured thereto by bolts a a, which also serve to secure the side clevises O O to said beams. Depending from the land-beam A to the rear of the land and furrow wheel axlearms D and D and secured to said beam by a belt I) is a bracket-bearing E, having a horizontal cylindrical aperture or bearing 6 through its lower portion. Bearing in this aperature e is a rod E, to the outer end of which is secured the operating-lever F.

-F designates an arm having an angular tapered aperturefin its lower end, which is engaged by a correspondingly-shaped portion f on the inner end of the rod E and is secured on said rod by a nut f In the upper end of the arm F is an aperture g, in which rests the rectangular end of a link-rod G, passing therethrough sufficien tly far, as shown at G to prevent it from falling out when the lever F is raised to the limit of its movement. The opposite end of this rod or link is connected to the hanger P of the rear wheel P for the purpose hereinafter described.

When the leverF is raised, it carries with it, as will be seen, the arm F. lVhen said lever is depressed, a shoulder g on the under side of the rod G is engaged by the arm F and forces said rod rearwardly, together with the hanger P, depressing the rear wheel P and elevating the rear ends of the plows above the level of the ground for facilitating turning corners, &c.

The furrow-wheel axle-arm D is provided with loose bearings 01 depending from and secured to' the furrow-beam, and has a rearwardly-projecting arm D on which is journaled the furrow-Wheel D The land-wheel axle-arm D has similar bearings on a casting 01 secured to the beam A, and has an arm D, on which is journaled the land-wheel D I-I designates an arm on what I preferably term a cam-link, which is secured at its lower portion to the land-wheel axle-arm bya key h and set-screws h. The upper partor head of this link is cut out, as shown, to form a cam-edged aperture H, in which travels a roller I, journaled on a pin or stud i of an arm I, secured to the axle-arm D of the furrow-wheel. The link H is connected to the lever F by means of a hinged link J, adjustably connected to said lever. Consequently when the lever F is depressed it carries with it the link H, and thereby brings the land-wheel to a level with the furrowwheel. lVhen this level is reached, the lever F being still further depressed, the roller I is engaged by an arm H of the cam-slot H, and when the lever is at the limit of its movement said arm is engaged by the bottom wall of said slot and both land and furrow wheels are depressed to raise both plows out of the ground. lVhen, however, said lever is thrown to the other limit of its movement, the roller I clears the arm H of the slot H and the link is carried forward until said roller rests against the opposite wall of the slot H. In this position the axle-arms will be raised, setting the plows to their full depth in the ground. This construction secures the independent action of the arm carrying the land-wheel in raising and lowering said wheel to vary the depth of the furrow without changing the position of the furrow-wheel, which will remain, while the plowis at work, level with the bottom of the plowsharesuntil the landwheel by the depression of the lever is brought to a level with the furrow-wheel. Continuing the depression of the lever by the action of the cam-slot and roller, the arms of both wheels are caused to take hearings on the wheelsand the plows are lifted clear of the ground, By means of the connection G to the rear wheel-hanger the rear portions of the plows are elevated at the same time by the same operation. The lever is held to the proper adjustment by a pawl K and pawl-lever K thereon, said pawl engaging any one of a series of teeth on the segment arm or rack K projecting upwardly from the landbeam.

To hold the arm I to its position when the plows are in the ground to their full depth, I provide the dog L. This dog is pivoted to a dog-plate L, carried by an arm or projection of the bearing d for the land-axle. When the plows are their full depth in the ground the dogL drops on an inward projection l on the arm I and secures said arm in position. When the lever is depressed, a projection M on the back of the link I-I comes in contact with a stud projection '11, on the dog, lifting it from engagement with lon the arm I, permitting said arm to be actuated by the engagement of the cam-slot with its roller to level up the furrow-wheel. The dog when down rests on a projection O on the dog-plate. A projection N on said plate serves as astop for the arm I when the plows are leveled up.

The rear wheel P is hung in a yoke Q, the arms of which are clamped at their forward portions to a bearing-block Q on the lower portion of the hanger P. This hanger P is carried in a bracket-arm R of the plow-beam A, which hasavertical slot or chambers therein, through which said hanger passes. Said hanger is-pivoted at 7' in the walls of said chamber, the pivot-bolt therefor serving, also, to secure the foot-rests s to the bracket-arm. The chamber or slot S is of sufficient size to allow the hanger to oscillate therein on its pivot. It will therefore be apparent that when the lever Fis depressed the hangerPis moved on its pivot to cause the wheel P to take a bearing on the ground to elevate the rear portions of the plows. When the lever is raised, the hanger is moved reversely to elevate the wheel and permit the plows to enter the ground.

On the bearing-block Q is a stud or projection T, which when the plows are lifted out of the ground is carried downward, swinging clear of the bracket it. When, however, the plows are in the ground, said stud or projection is thrown upward into engagement with a slot of the bracket. When in the former position, the rear wheel P has a swivel movement on the hanger; but when in the latter it will be held rigid, thus rendering said wheel a caster-wheel when the plows are out of the ground and a set wheel when they are in the ground. The projection T is usually of rounded form, the corners of the socket or slot in the bracket being similarly rounded. This construction is provided in order that when turning asquare-corner furrow withoutlifting the plows from the ground the lateral strain brought on the rear wheel by the team in pulling the plow sidewise to get in line with the furrow at right angles to the one finished may cause said projection to ride out of the socket or slot, falling again into place when the plow gets into line with the new furrow. This serves to keep the rear wheel sufficiently rigid to track in line and steady the plows when at work, but allows it lateral movement when any great strain is brought upon it, as in turninga square corner with the plows in the gronnd,as above stated.

U designates the seat-springy which is adjustably held to the bracket-arm R by the clamp U, consisting of the apertured lugs W, through which said spring passes, and the binding-screws to, having bearings in said lugs.

The rear wheel P is leveled up by means of the set-screw V, which has hearings in an upper projection V of the bracket-arm R and engages the hanger P to regulate its normal position in said bracket and the consequent adjustment of the wheel. r

V is a bolt for leveling up the plow-points, said bolt being connected to the landside of the plow and having a threaded engagement with a lug Q) on the plow-beam.

The dog-plate L is held to the arm or projection of the bearing d by means of a bolt passing through an arc-shaped slot in said dog-plate. By moving said plate forwardly or rearwardly on said bolt it will change the position of the arm I, which will carry with it the arm carrying the furrow-wheel, enabling the operator to set the furrow-wheel on a level with the bottom of the plowshare or above or below, as may be desired, or to perform what is known as leveling up.

To assist in operating the plows by the le- Ver F, the axle-arms D D between the two beams are each provided with a collar W, held thereto by a set-screw 10. Each collar has a projection U in which are formed seats or pockets a.

V are curved springs, each having one of its ends seated against the rear wall of the pocket of one collar and its other end against the rear walls of the pocket of the other collar. The tension put upon the springs by the upward movement of the lever F assists in lifting the plows out of the ground in'its downward movement.

movement, the springsare at rest and the plows are out of the ground. The rear walls of the pockets, against which the ends of the springs bear, resist the thrust of the springs when put under tension by the upward movement of the lever. One or more springs may be employed.
